Abstract

"PROCESSO PARA PRODUçãO DE AGLOMERADOS DE MINéRIO DE FERRO COM USO DE SILICATO DE SóDIO CONTENDO AGLUTINANTE". A presente invenção refere-se a um processo para produção de aglomerados de minério de ferro compreendendo aglomerar-se partículas finas de minério de ferro na presença de um sistema aglutinante onde o sistema aglutinante compreende um aglutinante e um silicato de metal alcalino e onde o silicato de metal alcalino está presente em uma quantidade de entre 0,0001 e 0,08 por cento em peso, com base no peso total do aglomerado de minério de ferro seco, onde o sistema aglutinante é livre de polímeros sintéticos, e preferivelmente compreende carboximetil celulose como aglutinante."PROCESS FOR THE PRODUCTION OF IRON ORE AGGLOMERATES USING SODIUM SILICATE CONTAINING BINDING". The present invention relates to a process for producing iron ore agglomerates comprising agglomerating fine iron ore particles in the presence of a binder system wherein the binder system comprises a binder and an alkali metal silicate and where the silicate Alkali metal is present in an amount of between 0.0001 and 0.08 weight percent, based on the total weight of the dry iron ore agglomerate, where the binder system is free of synthetic polymers, and preferably comprises carboxymethyl cellulose. as a binder.
